All releases of Syncless

Release Notes: This version was completely rewritten so it has drop-in replacements for the built-in Python functions such as socket.socket, socket.gethostbyname, ssl.SSLSocket, time.sleep, and select.select. The replacement implementations can be easily monkey-patched, so legacy (blocking) pure Python I/O code can be made non-blocking without a code change. Core functionality is now written in Pyrex/Cython for greater speed.
